摘要

基于Eyring的速率过程理论

并考虑了提供分子从一个平衡位置向另一位置迁移所需新位置的频率

得到了二元混台物粘度与过量吉布斯活化自由能间的关联式: K发现过量吉布斯活化自由能(?)对于相应的过量吉布斯自由能(?)有一通用比值

新位置的提供频率是组成和温度的函数.对10对二元系统(其中3对是水溶液系统)的粘度计算值与相应的55套数据进行比较

结果较为满意

均方根差为0.002一0.009.

Abstract

Based on Eyrings theory of rate processes

and taking into consideration the frequency of availability of new sites for passage of molecules from one equilibrium position to another

an equation relating viscosity of a binary mixture to its excess Gibbs free energy is The excess Gibbs free energy of activation G*E was found to have an optimum common ratio with respect to the corresponding excess Gibbs free energy GE. The frequency of availability of new sites is a function of composition and temperature. The calculated viscosity values for 10 binary systems (among which 3 are aqueous systems)

cotnpared with 55 sets of corresponding data

were satisfactory

with a deviation range of RMS=0.002-0.09.
